The scenario.sh login command should attempt console connection to hosts that have no ssh / NIC configuration. It is convenient when testing offline configurations, e.g. `test/scenarios/periodics/el94-src@offline.sh`

This requires the following setting in `test/kickstart-templates/includes/post-system.cfg` for example.

# Enable the getty service to allow VM access from the hypervisor using the
# 'virsh console vm-name' command.
systemctl enable serial-getty@ttyS0.service
